DICKERSON G. BAKER, OF WILLIMANTIC, CONNECTICUT.

COP-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 599,488, dated February22, 1898. Application filed December 11,1896. Serial No. 615,806. (Nomodel.)

To all whom, it may concern.-

Be it known that I, DICKERSON G. BAKER, of WVillimantic, in the countyof W'indham and State of Connecticut, have invented a new and usefulImprovement in Cop-\Vinding Machines,of which the following is aspecification.

My invention relates to an improvement in machines for automaticallywinding successive cops or sets of cops upon cores and for automaticallydischarging the wound cops.

In the accompanying drawings, Figure 1 is a view of the machine in frontelevation, showing one set of cop winding and discharging mechanisms inposition, it being understood that in practice several such sets may bearranged side by side, mounted in the same general frame, and driven bya common driving-shaft. Fig. 2 is a view in end elevation. Fig. 3 is anenlarged View, partly in end elevation and partly in section, of theoperative parts, exclusive of the drive'shaft. Fig. at is a top planview of the same. Fig. 5 is a partial front view of the same. Fig. 6 isa partial rear view of the same. Fig. '7 is a vertical section taken inthe plane of line 7 7 of Fig. 8, showing a part of the operatingmechanism in front elevation and a part in sect-ion. Fig. 8 is atransverse section through the master cam-cylinder, showing theconnection of the actuating-spring with the cylinder and the shaft onwhich the cylinder is mounted; and Figs. 9, 10, and 11 show in detailthe several positions which the cop-receiverand core-reservoir assumewith respect to the winding-spindle.

My invention, in the particular form in which I have at present embodiedit, contemplates means for presenting hollow cores, one after another,at intervals in a position in alinemen't with the winding-spindle meansfor advancing the winding-spindle to engage the core; means forimparting a retrograde movement to the spindle to carry the core thereoninto position to receive the thread; means for rotating the spindle towind several different cops of thread on the core; means for subdividingthe core into parts corresponding to the number of cops being wound, andmeans for discharging the wound cops into a receiver, the severaloperations being automatically repeated as long as may be desired.

The supporting-frame of the machine conveniently consists of ends A,(one only being shown,) terminating in legs a a. The said ends A areconnected by girders a a which may be made of such length as may berequired to accommodate one or more of the winding and ejectingmechanisms, as maybe desired. I prefer at present to mount four suchmechanisms in a single frame.

A drive-shaft B, common to the several mechanisms, is mounted insuitable bearings in the ends A and carries'a drive-pulley Z), by whichpower is transmitted to the driveshaft from a suitable source, (notshown,) and a pulley b for each winding and discharging mechanism fortransmitting power from the shaft 13 through a belt 13 to thedrive-pulleys which actuate the winding and discharging mechanisms.

The supporting-frame A a a a a is surmounted by a frame C forsupportinganumber of thread-supply spools c in position to deliver thedesired number of threads to the guide and thence to the spindle,according to the number of cops to be simultaneously wound.

The Winding-spindle is denoted by D. It is secured in a holder cl, whichembraces and has a longitudinally-sliding movement 011 the spindle-shaftd, the connection between the two being the ordinary spline-and-grooveconnection, by which the spindle-holderis caused to rotate with thespindle-shaft whatever he the longitudinal adjustment of the holder. Thespindle shaft and holder are mounted in stationary bearings 612 d and onthe shaft d there is fixed a gear-wheel (P, which intermeshes with alike gear-wheel E, fixed on a shaft 6, parallel with the shaft d,andextending from the front of the main frame to form a support for thecop-receiver and core-reservoir. The shafts has fixed thereon awormwheele, which intermeshes with a wormwheel F, fixed to rotate withadrive-pulley f, loosely mounted on a sleeve f, (see Fig. 6,) whichsleeve has mounted therein a shaft f carrying a drive-pulley f locatedadjacent to the drive-pulley F, and a Worm f for actuating the mastercam-cylinder, to be hereinafter particularly explained.

The cop-receiver, comprisinga rotary tubular'section G and a non-rotarytubular section G, and the core-reservoir H, located a short distancefrom and at the side of the tubular section G, are supported upon atubular base or housing I, the ends of which are mounted in rockingadjustment on the for- Wardly-projecting end of the shaft 6. The rotarysection G of the cop-receiveris mounted in a cylindrical bearingt' inposition to be swung in front of the winding-spindle D,with its axis ofrotation in alinement with the axis of the spindle, and the bottom ofthe corereservoir is also so located as to bring a core in, restingtherein, into axial alinement with the winding-spindle as the support Iis rocked on the shaft 6. The rotary section G is in alinement with thenon-rotary section G of the receiver and is provided with a gear-wheelg, fixed to rotate therewith,which gear-wheel intermeshes with agear-wheel g, fixed on the shaft 6. The gears g g correspond to thegears d E, so that the rotary receiver-section G and the spindle willrotate at the same speed. The interior of the section G is provided withspring retaining-hooks g in the present instance three in number andlocated at equal distances apart around the receiverso seated inrecesses g in the interior wall of the receiver that they may be readilyforced outwardly as the wound cops are passed into the receiver topermit the cops to pass freely, but adapted to springinwardly after thecops have passed their hook ends to prevent the withdrawal of the cops.The section G of the receiver is somewhat choked by springtongues 9which project slightly from the inner wall of the receiver to hold thecops, which may have been forced therein from the rotary section G, inposition until they are forced from the receiver by the thrust of asucceeding set.

The rocking support I has a hub extension 11 through the front of thesupporting-frame and has clamped to it an arm i which may beasector-arm, by which the support I and parts carried thereby are rockedbodily on the shaft 6 through a connecting rod or bar K, controlled bythe master cam-cylinder, as will be hereinafter more particularlydescribed.

On the shaft e there is a sleeve 6 which extends from a point within thehousing I through the hub 2". The sleeve c has mounted thereon withinthe housing I the threadguide arm L, the connection of the guide-armwith the sleeve being made by trunnions Z, projecting radially from theopposite sides of the sleeve to permit the arm to be vibrated in theplane of the axis of the sleeve, while at the same time subject to rockwith the sleeve.

The thread-guide proper is denoted by Z, (see Fig. 7,) and maybe of anywell-known or approved form adapted to distribute the several threads topositions on the windingspindle to form the several cops to be wound andsubject to the gradually-increasing size of the cop to be pushed awayfrom the spindle and through its swinging movement to rock the sleeve 6and a trip-dog Z carried by the sleeve, to stop the winding-spindle whenthe cop has reached a predetermined size, as will hereinafter moreparticularly apear.

p The sleeve 6 has the trip-dog Z fixed to it at 6 within the housing I,and it also has fixed thereto exterior to thehousing I an arm 6 forsustaining a Weight 6 to counterbalance the dog Z and give thethread-guide the desired pressure against the periphery of the cop beingwound.

The shaft 6 has fixed to rotate therewith a disk E, the inclined face ofwhich bears against the guide-arm support and serves as the shafterotates to impart a vibratory movement to the thread-guide in adirection transverse to that in which the thread is fed to lay thethread obliquely on the periphery of the cop being wound.

The part which I have chosen to designate as the master cam-cylinder isdenoted by M. It is mounted to rotate on a sleeve on, supported parallelwith the spindle-shaft, and has formed in its exterior curved surface acamgroove consisting of two V-shaped portions m m separated by a shorterannular portion m and a longer annular portion on. An arm N, mounted ona guide rod or bar at to slide freely along its support parallel withthe spindle-shaft, projects into the cam-groove m m m m and iscontrolled in its sliding movement by said cam-groove as the cylinder Mis rotated. The arm N also embraces the winding-spindle holder clbetween two abutments d and d thereon, as shown at n, Fig. 3, so thatthe movement of the arm N under the control of the cam-groove in thecylinder will move the spindle-holder, and hence the spindle D,longitudinally forward and backward as the arm travels along theV-shaped portions of the cam-groove.

The cam-cylinder M is further provided with a cam-groove in its frontend for operating the bar K, hereinabove referred to, to rock thecop-receiver and core-reservoir back and forth to present the receiverand a core alternately in front of the winding-spindle. The saidcam-groove consists of three annular portions, denoted, respectively, by7c 70 and intermediate straight portions, denoted by 70 10 (See Fig. 7.)This cam-groove receives. a laterally-projecting roller 10 on the bar K,and as the said roller travels along the groove during the rotarymovement of the cylinder imparts to the bar K, and hence to thesection-arm 2' with which the bar K engages by means of rack-teeth-k onits under side, a positively-reciprocating movement to present a core tothe spindle and a secondary IIO reciprocating movement to bring thecutters out of and into engagement with the core to subdivide it. Theoperating-bar K has one end bifurcated, the branches 71: k embracing theopposite sides of a hub at the end of the cylinder M to serve as a guidefor the bar.

The core-cutters hereinabove referred to consist of a series of sharpdisks 0, fixed at suitable distance apart on a rotary spindle 0,supported in standards 1' 2", fixed to the support I. The distancebetween two successive cutters O is made slightly greater than thethickness of a cop for the purpose of severing a core 1) into partshaving lengths as nearly as may be equal to the thickness 'of a cop.

The master can1-cylinder M is positively ro tated when the belt 6 isshifted onto the pulleyf by means of the worm f on the shaft f whichworm engages an annular series of worm-teeth m on the periphery of thecylinder M.

The shifting of the belt 6 from the pulley f, which drives thewinding-spindle, on to the pulley f then onto both pulleys f and f andfinally back again onto the pulleyfto effect the several operations ofdischarging the wound cops, receiving a new core, starting the winding,and subdividing the core is accomplished as follows: Through the sleevem, on which the master cam-cylinder is mou nted, there extends a shaftP, which has fixed to its front end a cam wheel or disk 13 and to itsrear end a disk 1), provided with a cam-groove 17 The cam-disk 1) has aportion of its periphery cut away, forming an abrupt abutment p forengaging the nose of the trip-dog Z and a gradual incline p forpermitting the nose of the trip-dog to gradually assume a position toengage the abutment 19 The abutment 19 during its rotary movement, whenreleased from the trip-dog Z is caught and the rotary movement of theshaft P and disks thereon interrupted at intervals by retaining-pawls Qand Q, actuated in any well-known or approved manner. The pawls Q and Q,are pivoted to the supporting-frame and have a beveled lifting-surface qq, offset laterally from the hook portion to clear the abutment 19 butin position to engage a releasing-tappet g fixed on the periphery of ahub m projecting forwardly from the end of the master camcylinder M. Theshaft P is actuated by a coiled spring P, one end of which is fixed tothe shaft and the opposite end to the interior of the hub m"'in such amanner that its tension will tend to rotate the shaft P in a directionthe reverse of that in which the hands of a watch move as looked at fromthe front, and the rotary movement of the cam-cylinder about the shaft Pwill serve to wind the spring P after the rotary movement of the shaft Phas expended its force or part of its force, keeping it at all timesunder effective tension to rotate the shaft; As the shaft P is permittedto rotate by the release of the tripdog and retaining-pawls, it operatesthe belt shifter through the medium of the cam-groove p in the disk 19'as follows: The belt-shifter consists of a bell-crank lever pivoted tothe frame at R, its arm 9" extending into position to embrace theopposite edges of the belt 19 and its arm 1" being provided with alaterally-projecting roller r in position to follow the cam-groove 1J Abrake S, consisting of a flexible strap, has one end attached to theframe at s, and after passing around a brake-wheel on the shaft 6 hasits opposite end attached at s to the arm 1" of the beltshifting lever,so that when the arm r is moved to shift the belt from the pulleyfontothe pulley f the strap S will be drawn into close contact with thebrake-wheel on the shaft 8 and cause the said shaft and hence thewinding-spindle to promptly stop its rotary movement. WVhen the copsbeing wound have reached a predetermined size and have rocked the sleeve6 and the trip-dog carried thereby sufficiently to release the nose ofthe dog from the abutment 19 the shaft P will rotate quickly under thetension of its operating spring until its rotary movement is arrested bythe engagement of the abutment p with the retaining-pawl Q. This partialrotation (in this case a half-revolution) of the shaft P, carrying withit the grooved camdisk 19, will rock the belt-shifter its full throw,shifting the belt 6 from the spindledriving pulleyfonto thedriving-pulley f and through the action of the brake S promptly stoppingthe rotary movement of the winding-spindle and also of the rotarysection of the cop-receiver. The master camc'ylinder will then begin torotate in the same direction as the shaft P was rotated by the shaft fand worm f and will continue its rotary movement until the belt has beenentirely removed from the drive-pulleyf The belt will remain wholly onthe drive-pu1ley f and the winding-spindle be prevented from a rotarymovement while the cylinder H is completing three-fourths of a rotation,:more or less-that is, while the releasing'tappet g is being carriedfrom its position shown in Fig. 7 to a position to lift theretaining-pawl Q and again release the shaft P. During this two-thirdsrotation of the cylinder M, more or less, the two V-shaped portions m mand the intermediate annular portion m of the cam-groove in the curvedface of the cylinder will have operated upon the spindle-holder d, withthe following results: The spindle, with the wound cops thereon,willhave been thrust into the rotary section G of the cop-receiver andwithdrawn from the same, leaving the cops therein. This will have beenaccomplished by the V- shaped portion m of the cam-groove. WVhile thishas been taking place the roller is on the operating-bar K has beentraveling along the circular portion of the cam-groove in the front endof the cylinder M and has not disturbed the position of the cop-receiverrelatively to the windingspindle. -At this point, however, and while thespindle-holder d, and hence the spindle,

are held in the normal position by the engagement of the annular portionm of the cam-groove with the arm. on the spindleholder, the bar K isforced to the left by the straight or tangential portion of the groovein the end of the cylinder, and the support I, and hence thecop-receiver and core-reservoir, are rocked to the left, bringing thecore at the bottom of the reservoir into alinement with the spindle. Thecore-reservoir is held in this position by the engagement of thecircular portion 7a of the cam-groove with the roller 70 while the Vshaped portion m of the cam-groove in the curved surface of the cylinderimparts to the spindle a second forward-and-return movement-a forwardmovement to enter a core and a return movement with the core thereon. Atthis moment the retaining-pawl Q is released by the tappet g and theshaft P turns around until it is stopped by the engagement of the secondretaining-pawl Q with the abutment 19 This partial rotation of the shaftP, through the medium of the cam-groove in the disk 19, will operate thebelt-shifter to shift the belt into position partly on each of thedrive-pulleys f and f and will thereby start the rotation of thewinding-spindle, while the rotation of the master cam-cylinder will becontinued. The portion-m of the cam-groove in the curved surface of thecylinder being annular, the position of the spindle will not be furtheraffected. The straight portion 70 of the camgroove in the end of thecylinder will, through the operating-bar K, rock the support I overtoward the right while the winding of a new set of cops is beingstarted, the threads from the previously-wound set leading from withinthe rotary section G of the receiver out around the core on which thenew set is being wound and the said previously-wound cops being rotatedin the section G at the same rate at which the winding-spindle isrotated. The rocking movement of the support I will be continued by theportion 70 of the camgroove until it has brought the cutters 0 intoengagement with the core h to sever it and the threads between the cops,and the short circular portion 70 of the groove serves to hold thecutters there a little time, when the following straight portion of thegroove serves to rock the support I a short distance back to the left tomove the cutters out of engagement with the cores and bring the sectionG of the receiver in alinement with the spindle ready to receive thewound cops. At this moment the tappet g releases the second reandretracting the spindle, a cop-receiver and core-reservoir and means formoving them into and out of alinement with the spindle, substantially asset forth.
